Detailed explanation-1: -The membrane of mitochondria is semi permeable in nature to allow the entry and exit of molecules. There are two kinds of membrane present in the mitochondria.-Outer membrane-It is a phospholipids bilayer which has several integral membrane proteins called the porins.
Detailed explanation-2: -The inner membrane forms invaginations, called cristae, that extend deeply into the matrix. The cristae define the third mitochondrial compartment, the crista lumen. The crista membranes contain most, if not all, of the fully assembled complexes of the electron transport chain and the ATP synthase (Fig. 2).
Detailed explanation-3: -2) The outer mitochondria membrane is a phospholipid bilayer embedded with integral proteins.
